Error number: 33: SessionNotCreatedError session not created exception from unknown error while trying to simulate chrome browser using SeleniumBasic

Question

I have been using the COM interface provided by Internet Explorer but, since some sites have now moved on and don't support IE, I have been looking to substitute this with SeleniumBasic.

As this is completely new to me, I'm at the very basic level - I've downloaded the Selenium Type Library (I've downloaded the Selenium library reference from Github, and referenced is in the module).

I've put in a very basic bit of code to test it out but I'm getting the following error:

Error number: 33 Error description:

SessionNotCreatedError session not created exception from unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"AE85B634088DDFB4B8E7D65A145ADA0F","isDefault":true},"id":1,"name":"","origin":"://"} (Session info: chrome=69.0.3497.100) (Driver info: chromedriver=2.21.371459 (36d3d07f660ff2bc1bf28a75d1cdabed0983e7c4),platform=Windows NT 10.0 x86_64)

The code is;

Sub TestCode()
Dim driver as New Selenium.Chrome

driver.get "www.Google.com" 

End Sub

I've tried this with firefox and Edge browsers too but am getting the same issues - any suggestions on what might be going wrong?

Solution

This error message...

SessionNotCreatedError session not created exception from unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"AE85B634088DDFB4B8E7D65A145ADA0F","isDefault":true},"id":1,"name":"","origin":"://"} 
 (Session info: chrome=69.0.3497.100) 
 (Driver info: chromedriver=2.21.371459 (36d3d07f660ff2bc1bf28a75d1cdabed0983e7c4),platform=Windows NT 10.0 x86_64)

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chromedriver=2.21
• Release Notes of chromedriver=2.21 clearly mentions the following :

Supports Chrome v46-50

• You are using chrome=69.0
• Release Notes of ChromeDriver v2.42 clearly mentions the following :

Supports Chrome v68-70

So there is a clear mismatch between ChromeDriver v2.21 and the Chrome Browser v69.0

Solution

• Upgrade Selenium to current levels Version 3.14.0.
• Upgrade ChromeDriver to current ChromeDriver v2.42 level.
• Keep Chrome version between Chrome v68-70 levels. (as per ChromeDriver v2.42 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Execute your @Test.

Update A

As per florentbr/SeleniumBasic the last version of SeleniumBasic (A Selenium based browser automation framework for VB.Net, Visual Basic Applications and VBScript) seems to be Release v2.0.9.0 only.

As per the CHANGELOG of Release v2.0.9.0 the underlying components are:

• Firefox driver version 2.52.0
• IE driver version 2.52.1

Update B

If you intend to use GeckoDriver with Firefox you can following the matrix below:

Thanks for the answer! I've downloaded the Selenium .jar file but I can't figure out to include this in my reference library - can you give me a bit of a steer? Again, thank you very much!

I am afraid as I work with Java/Python/NodeJS bindings only but not Basic/vba. The issue was quite clear and evident so tried to help you out. Wait for @QHarr to have a look at this counter question.

[Jeremy]

@QHarr I'm sorry to dragging you into this but would you be able to help here? I did download the Selenium wrapper but it was the 2.9 version which doesn't work for me - is there a 3.14 version of VBA (I can't find it anywhere!!)?

[undetected Selenium]

Checkout the update within my answer, may be you will be able to pull out something useful.

[Jeremy]

Thanks, that was my suspicion - So really what I would need to do is downgrade a browser and then use that (probably Firefox, which is throwing up the same error)?

[undetected Selenium]

Checkout the update within my answer and let me know the status.

[Jeremy]

I do appreciate you efforts but the oldest version Selenium listed is 3.4 whereas the newest version available to me (for VBA) is 2.9. I was hopeful for this beforehand but I'm starting to think I'm out of my depth! Are you aware of any other alternatives to Selenium?

[undetected Selenium]

Don't loose your attention. Configuration is a one time effort. I am sure you are close to a working configuration. If you are stuck some where else feel free to raise a new question with your new requirement. @Florent B. (SeleniumBasic creator) is active here as well and would be able to guide you in a moment. Added some more update within my answer.

[Jeremy]

Thanks for your help - I've just downgraded my chrome to v49 and only use the ChromeDriver. I appreciate your patience with me!

[QHarr]

Sorry I didn't see any of these messages as I hadn't interacted with the thread. But actually swung by looking for a similar post and came across this. Great answer @DebanjanB + . Do you mind adding in the Chrome info to update A (or was that missing from any available documentation? - it used to be you couldn't use FF > than v.46.0.1. but Chrome you were ok so long as binary went with Chrome version. I would like to be able to use this as a dupe target (i.e. send people here)
